In Indonesia, large areas of forest were lost and extensive oil palm plantations were established over the last decades. We conducted a combined social and environmental study in a region of recent land-use change, the Jambi Province on Sumatra. The objective was to derive complementary lines of arguments to provide balanced insights into environmental perceptions and eco-hydrological processes accompanying land-use change. Interviews with villagers highlighted concerns regarding decreasing water levels in wells during dry periods and increasing fluctuations in stream flow between rainy and dry periods. Periodic water scarcity was found to severely impact livelihoods, which increased social polarization. Sap flux measurements on forest trees and oil palms indicate that oil palm plantations use as much water as forests for transpiration. Eddy covariance analyses of evapotranspiration over oil palm point to substantial additional sources of evaporation in oil palm plantations such as the soil and epiphytes. Stream base flow from a catchment dominated by oil palms was lower than from a catchment dominated by rubber plantations; both showed high peaks after rainfall. An estimate of erosion indicated approximately 30 cm of topsoil loss after forest conversion to both oil palm and rubber plantations. Analyses of climatic variables over the last 20 years and of a standardized precipitation evapotranspiration index for the last century suggested that droughts are recurrent in the area, but have not increased in frequency or intensity. Consequently, we assume that conversions of rain forest ecosystems to oil palm plantations lead to a redistribution of precipitated water by runoff, which leads to the reported periodic water scarcity. Our combined social and environmental approach points to significant and thus far neglected eco-hydrological consequences of oil palm expansion."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2016"],["dc.identifier.doi","10.5751/ES-08214-210205"],["dc.identifier.fs","620597"],["dc.identifier.gro","3147091"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13227"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/110156"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-575"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | A | A02: Wassernutzungseigenschaften von Bäumen und Palmen in Regenwald-Transformationssystemen Zusammenfassung"],["dc.relation","SFB 990 | A | A03: Untersuchung von Land-Atmosphäre Austauschprozesse in Landnutzungsänderungs-Systemen"],["dc.relation","SFB 990 | A | A04: Carbon stock, turnover and functions in heavily weathered soils under lowland rainforest transformation systems"],["dc.relation","SFB 990 | B | B10: Landschaftsbezogene Bewertung der ökologischen und sozioökonomischen Funktionen von Regenwald- Transformationssystemen in Sumatra (Indonesien)"],["dc.relation","SFB 990 | C | C02: Soziale Transformationsprozesse und nachhaltige Ressourcennutzung im ländlichen Jambi"],["dc.relation.issn","1708-3087"],["dc.relation.orgunit","Fakultät für Geowissenschaften und Geographie"],["dc.relation.orgunit","Abteilung Ökosystemmodellierung"],["dc.relation.orgunit","Abteilung Bioklimatologie"],["dc.rights","Goescholar"],["dc.rights.access","openAccess"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","eco-hydrology; environmental perception; erosion; evapotranspiration; forest; land-use change; runoff; rural water supply; streamflow; transpiration"],["dc.subject.gro","Eco-hydrology"],["dc.subject.gro","Environmental perception"],["dc.subject.gro","Erosion"],["dc.subject.gro","Evapotranspiration"],["dc.subject.gro","Forest"],["dc.subject.gro","Land-use change"],["dc.subject.gro","Runoff"],["dc.subject.gro","Rural water supply"],["dc.subject.gro","Streamflow"],["dc.subject.gro","Transpiration"],["dc.subject.gro","sfb990_journalarticles"],["dc.title","Water scarcity and oil palm expansion: social views and environmental processes"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The island of Sumatra in particular is severely a ff ected by the rapid expansion of monoculture cash crops. Since Dutch colonial times, land tenure regulations here have generally favored such resource exploitation. The current National Development Plan continues to see Sumatra as a center of resource production in order to eradicate poverty and accelerate national development. This developmental focus, however, is accompanied by contested land use scenarios. Taking a historical perspective, this research discloses di ff erent layers of past and present land tenure regulations to understand present contestations of land use, resource exploitation, and their social consequences. Based on a village case study, the research demonstrates how di ff erent political eras and their accompanying land tenure approaches are inscribed in today's local landscape. We found that de jure regulations which were added to customary laws created a situation of legal pluralism.
